Work Breakdown Structure

Issue: A fixed budget is allocated for the CERN AWAKE project. This corresponds to what we have asked for in the Design Report.

In order to have first beam in September 2016, the schedule is very tight!! Also we have to consider the general CERN schedule for the accelerators!

Electron Tunnel (Beginning December 2013)


C. Magnier, F. Galleazzi


Issue:Start digging tunnel mid 2014!Define electron tunnel specs in January 2014. Specifications for electron beam must be frozen! A lot of work for integration, transport, beam

instrumentation, magnets, services, etc….


Electron Beam Tunnel


Proton tunnel1st floor: Cooling & Ventilation

Issues:All drawings will be implemented into CERN system. Also from the experiment! Use CERN standard:

CATIA, step files!

21

Electron Source Area


S. Girod, V. Clerc

PHIN injector used as baseline here. No services yet included. Tight area.

22

Electron Source Area


S. Girod, V. Clerc

Issue: We need to know more about the electron source to advance with integration studies

and to consider all services needed. Space constraints! Fit the electron source to the AWAKE needs!

23

Laser Beam Line


Issues:Placement of optical compressor and telescope needs to be clear before defining the exact position of the drilling. urgently needed! Vacuum components – up to 10-8 mbar?

Decay Tube Window


Result: We can leave the shutter closed even when we have beam. Leave vacuum inside the decay tunnel (less air - contamination) If ever (!!) we have access during beam, OK from decay tube safety point of view.

Maximum energy deposited at decay tube window (shutter): 0.2 (2.5) J/cm3/pulse

Maximus stress in window below yield strength of Ti

Very low temperature increase in window and shutter due to beam

Issues: Extremely challenging with the current beam specifications to squeeze the electron

and proton beam into the plasma cell! Beam diagnostics around the plasma cell not clear. Rethink plasma cell design (size)? Or keep firm parameters for electron gun! Facility geometry gives limits to electron source design!

WP2 SPS Beam


• Example of Sub-WP: RF synchronization of proton, electron, laser beam. – Electrons from RF gun driven by a laser pulse derived from same laser system as used for ionization.

Synchronization between laser pulse and electron beam at < 1ps can be achieved. – Synchronization of proton beam w.r.t. laser beam at ~100ps level is desired:

SPS RF must re-phase and lock to a stable mode-locker frequency reference from laser system.

Summary

• We install an experiment into an existing facility – and not a facility around an experiment! – Many constraints.– Need well-defined specifications and strategies!

• E.g. what is the strategy for the electron beam?• E.g. where will be the laser bunch compressor installed?• E.g. what is the electron spectrometer layout?

• AWAKE is an accelerator R&D experiment! – Beam is not simply delivered and the experiment is not stand-alone with its own

electronics, readout, etc…– The experiment is fully integrated into the accelerator complex

• Very close collaboration with institutes that build equipment is needed– CERN standards must be used!

• Drawings: CATIA, step-files.• Software, DAQ see Roman’s talk, Thu 5 Dec, 14:00! • Interface issues

– Advantage: profit from CERN support.

– Necessary modifications of the civil engineering and general services of the AWAKE facility.

– Optimization of the beam parameters. Production of the AWAKE proton beam in the SPS and in the transfer to the experimental area, within specifications.

– Electron beam studies in the plasma cell.– Development of the diagnostic instrumentation along the beam lines and in the

experimental area. – The coordination and installation of the experimental equipment delivered by the

collaboration, including interface design and construction support.– The coordination of all radiation protection and safety aspects.– Coordinate the studies of all interfaces between the different systems (plasma cell,

electron beam, proton beam, laser…), including studies on the measurement program– Take responsibility for all safety aspects. Prepare safety files. – Evaluate dismantling feasibility.
